intel-gem: Emit an MI_FLUSH at glFlush() so frontbuffer rendering is flushed.
We have something similar in the X Server that covers X Server rendering, this is the equivalent here for rendering to the front buffer. If we cared about avoiding this at glFlush time, we could only do this when some actual frontbuffer rendering had occurred. Bug #16392.
